The Development and Application of Climate Model in Paleoclimate Simulation

Climate simulation is to study climate change with climate models.According to the practical requirement of research climate change,many climate models including generally the General Circulation Models(GCMs),Earth System Models of Intermediate Complexity(EMICs) and simple climate models(SDMs,RCMs,etc.) are developed.Although there are some differences between different models in simulating the spatiotemporal scale of paleoclimate,modeling capability and suitable research fields of climate change,these models have been extensively applied to analyze the causes and mechanism of climate change,understand the climate systems and formulate the climate policies.These models have their own limitation when they are applied to simulate climate change.In order to make the simulated results be close to the recorded data of climate change,the suitable model or models should be used in simulating climate change.It is considered that the climate simulation study will be significantly improved along with the improvement of computer hardware,simulation models,calculation methods and deep understanding to climate systems.
